SCULPTURING-MACHINE.

`.Application tiled March 24, 19111. l Serial No. 826,971.

To all 'whom t may concern j Be it known that 1 EDWARD M. COYNE, a citizen of the United States, residing at Pittsburgh, in the vcounty of Allegheny and State of `Pennsylvaniahave invented new and useful Improvements in Seulpturing- Machines, of which the following is a speciication.

The invention relates generally to sculpturing machines, being particularly directed to a mechanical structure through the use of which a reproduction in yplastic material may be made of any subject, the construction permitting the reproduction in variously prolportioned sizes with respect to the Vorigina The main object of the present invention is'the provision of a simple type of sculpturing machine, in which the model and plastic material are mounted on synchronously operated supports with a forming tool operating on the `material and controlled through the use of a guide element caused to follow the original through the use of connecting members, whereby the original is reproduced inthe plastic material.

The invention in vthepreferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, inV

which f Figure l is a view in* elevation .of the improved machine,` showing the same in use. Fig. 2 is a planof thesame, partly broken away. Fig. 3 is a section on line 3--3 of Fig. 1. Fig. 4 is a section on line l-tof 2. Referring particularly to the accompanying drawings, the improved machine includes a base 1 of .suitable type and size,fon

which preferably adjacent one end, is arranged a circular wall 2, within which, secured to the base, is a pedestal 3. A stub shaft d is rotatably supported in the pedestal 3, rbeing formed at the upper end with a bevel gear 5, which stub shaft. through the medium of the spacing block 6 is connected by bolts 7 to a supporting platformwS. Uprights 9 are secured to the platformthrough the medium of brackets 10, the uprights being preferably four in number and curved throughout their lengths for the forward portion of the platform, as shown. The uprights have inwardly extending,r longitudinally arranged ribs 11, which at an appropriate point are formed with shoulders 12, designed to provide supports for a seat13.

Specification of Letters Patent.

Patented Dec. 7, 1915.

The upper ends of the uprights support an inclosing frame made up in sections 14 and connected to the uprights by brackets 15, one of the sections having hinged connection at 16 with an adjacent section to permit entrance `to the interior of the frame provided by the `parts described. For convenience, two of the opposed sections 14: are cut out at 17 to form shoulder room in the event the original is a human being and the platform r8 is provided with a foot rest 19.

On the base 1 remote from the framework just described, is secured a pedestal 20, preferably of cruciform shape in cross section on the upper end of which are supported spaced bearingplates 21. A plate 22 is arranged between the brackets, and provided with opposing trunnions 23 to lit in bearing openings 24 formed in the plates 21. A disk 25 is rotatably supported on the plate 22, a

pivot 26depending centrally from thedisk Vand seating yin an opening y1n the plate.

The plate 22 between the trunnions is centrally depressed or offset, so that the disk 25 is in line with the trunnions, whereby the practically universal movement thus yprovided has its pivotal supports in the same plane.

An operating lever 27 is secured at its rear end on the disk 25 the forward endof the lever being yprovided with a lateral post 28, kthe free end of which is formed with a threaded socket 29 to removably receive the guide element 30. The guide element is formed at its free end for guiding coperation with the original to be duplicated, the

removable connection of said element with,y

the post permitting the convenient use `of different forms of such element. At a point mid-length the lever27, the latter is formed with a reinforced bearing opening 31, and at a point mid-distant between said opening 31 and the universal connection previously described, said lever is formed with a similar opening 32. In other words, the openings 31 and 32 are disposed respectively at one-half and 'one quart-er the length of` `the lever from its fulcrum these arrange-` ments being merely illustrative, as it is contemplated arranging theopenings at any appropriate points, in order that the reproduction or model may have `a definite proportion, previously determined bythe location of the opening used to .the original.

.A cutting tool is arranged Vto coperate with eitherof the openings 31 or 32, said tool including ya bearing sleeve 33 adapted 55 f Aappropriate mass of the desired material ar-V post 28, and a cutting tool 35 projecting from the sleeve inthevsame direction as the post. The projection of the cutting tool beyond the sleeve is directly proportioned to the length of the guiding element as is obviously necessary, and the tool is removably secured 1n the sleeve tov permit the use -of tools of dierenttypes. A bed rplate 36 is secured upon ther lever 27 above its fulcrum, said bed plate supporting a motor 37V connected by a belt 38 to a belt wheel 39 secured on the free end ofthe shaft 34,

"whereby rotative movement is imparted to the' cutting tool.

' In direct alinement with the centers of the platform 8 and of the fulcrum. of the lever 2,7, the base 1 is formed Vwith bearing openings 40 and 41, shown in the present instance jas located respectively at mid-length and quarter length the distance between such centers. A pedestal 42 is arranged to removably coperate with either `opening 40 or 41. A shaft 43 is rotatably mounted in the'pedestal, supporting at its upper end a plate 44. The shaft 43 is provided adjacent its lower end with ya bevel gear 45, and the bevel gears 5'and 45 are connected for synchronous operation by a shaft 46 supported at one end in the pedestal 3 and at the opposite end in a collar 47 secured within the 'pedestal 42. Y The shaft 46is provided with bevel pinions 48 andy 49lcoperating respectively with thebevel gears 5 and 45, so that uniform and simultaneous movement Vis imparted to the platform 8 and to the plate 44. That end ofthe shaft adjacent the terangular contour as at 50, whereby to permit the application of an extension shaft 51, when the opening 4l is used Vto receive the pedestal 42.

minal entering the collar 47 is squared or of The material to be formed in accordance 'with the original is preferably molded in a mass, vas 52'about a hollow angular holding i member 53 adapted to be secured to a plate 54, which is in turn removably secured to the plate 44. The holder will thus secure the f mass to permit it to be operated upon, the

holder lbeing preferably of aluminum.

In use, assuming as illustrated, the use of a living original, the subject is placed within the frame upon the platform 8, and an ranged upon the plate 44." In the rotation of the platform 8, which may be accomby hand as theoperator may nd necessary or desirable, vthe plate 44 is similarly ro- Vcorresponding portion of the model, .the

similar correspondingV portions maintaining the same relative positions atall times. The

operator by causing the guide element to follow theoutline of the original, will cause the cutting tool to follow a similar outline,

- and the latter by reason of its rotation will cut, chip, or otherwise form the material in exact accordance with the original.

It is thereforeapparent that, through the above described construction, I have provided a simple type of'machine, 'which will 75 nection with the plate 44.
